What is bc ? enter your answer in the box. units?

The length of the BC is 25 units .

Step-by-step explanation:

As shown in the diagram

In ΔABC  

∠B = ∠C (As given)

(If the angles are equal than their opposite sides are also equal .)

Thus

AB = BC

As given

AB = 4x + 4

AC = 6x - 14

Thus

4x + 4 = 6x - 14

6x - 4x = 14 + 4

2x = 18

x = 9

Put in the

BC = 2x + 7

     = 2 × 9 + 7

     = 18 + 7

     = 25 units

Therefore the length of the BC is 25 units .

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
